⚠️ Common Symptoms of Bad Ignition Coils or Spark Plugs:
When an ignition coil or cylinder begins to misfire on your Ford F150, the truck will show these classic, frustrating symptoms:
- Rough Idle & Heavy Shaking: The truck shakes heavily or vibrates violently when sitting at a stoplight or idling in the driveway.
- Engine Stumble & Hesitation: When you step on the gas pedal—especially under load or going up a hill—the truck hesitates, chugs, or jerks.
- Flashing or Steady Check Engine Light (CEL): Triggering specific OBD2 trouble codes like P0300 (random misfire) or P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 (denoting the exact cylinder that is failing).
- Severe Loss of Power: The engine feels sluggish and weak, struggling to pick up speed or tow anything.
- Poor Fuel Mileage: Unburnt fuel passes through the exhaust system, heavily impacting your gas mileage and creating a strong fuel odor.
